Sun in Ha - June 17, 2023

Acquisition type: Lucky imaging

The Sun in H-alpha on June 17, 2023 featuring one of the largest prominences I've capture in the past few years of solar imaging. The single stack images once again came out with better detail in the proms than the double stack images so posting those. These proms were vary faint and required long exposures for solar (33 msec vs my usual 10 msec for single stack prom images).

Imaged with a Lunt LS50Tha (with feathertouch focuser and ZWO EAF), Lunt LS50C compact double stack filter, 2.5x Televue Powermate, ZWO ASI290MM. Imaging train was configured to give ~F/18. Image capture using Firecapture. Stacking in AutoStakkert3 (best 25% of 1000 frames). Processed in Registax (sharpening). Blacked out the solar disk and colorized prom image using Solar Live View.

Original version: Prominence image processed Solar Live View (black and white version)

Rev B: Prominence image processed with LuSol3D and Solar Live View (colorized version)

Rev C: Added height references and representative Earth for scale using LuSol3D

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
